THE FIELD OF THE INVENTION

The present invention is in the field of soybean cultivar breeding and development. The present invention particularly relates to the soybean cultivar AR1319046 and its seed, cells, germplasm, plant parts, and progeny, and its use in a breeding program.

BACKGROUND OF THE INVENTION

Soybean Glycine max (L) is an important oil seed crop and a valuable field crop. However, it began as a wild plant. This plant and a number of other plants have been developed into valuable agricultural crops through years of breeding and development. The pace of the development of soybeans, into an animal foodstuff and as an oil seed has dramatically increased in the last one hundred years. Planned programs of soybean breeding have increased the growth, yield and environmental hardiness of the soybean germplasm.

Due to the sexual reproduction traits of the soybean, the plant is basically self-pollinating. A self-pollinating plant permits pollen from one flower to be transferred to the same or another flower of the same plant. Cross-pollination occurs when the flower is pollinated with pollen from a different plant; however, soybean cross-pollination is a rare occurrence in nature.

Thus the growth and development of new soybean germplasm requires intervention by the breeder into the pollination of the soybean. The breeders' methods of intervening depends on the type of trait that is being bred. Soybeans are developed for a number of different types of traits including morphology (form and structure), phenotypic characteristics, and for traits like growth, day length, relative maturity, temperature requirements, initiation date of floral or reproductive development, fatty acid content, insect resistance, disease resistance, nematode resistance, fungal resistance, herbicide resistance, tolerance to various environmental factors like drought, heat, wet, cold, wind, adverse soil condition and also for yield. The genetic complexity of the trait often drives the selection of the breeding method.

Due to the number of genes within each chromosome, millions of genetic combinations exist in the breeders' experimental soybean material. This genetic diversity is so vast that a breeder cannot produce the same two cultivars twice using the exact same starting parental material. Thus, developing a single variety of useful commercial soybean germplasm is highly unpredictable, and requires intensive research and development.

The development of new soybeans comes through breeding techniques, such as: recurrent selection, mass selections, backcrossing, single seed descent and multiple seed procedure. Additionally, marker assisted breeding allows more accurate movement of desired alleles or even specific genes or sections of chromosomes to be moved within the germplasm that the breeder is developing. RFLP, RAPD, AFLP, SSR, SNP, SCAR, and isozymes are some of the forms of markers that can be employed in breeding soybeans or in moving traits into soybean germplasm. Other breeding methods are known and are described in various plant breeding or soybean textbooks.

When a soybean variety is being employed to develop a new soybean variety or an improved variety, the selection methods may include backcrossing, pedigree breeding, recurrent selection, marker assisted selection, modified selection and mass selection or a combination of these methods. The efficiency of the breeding procedure along with the goal of the breeding are the main factors for determining which selection techniques are employed. A breeder continuously evaluates the success of the breeding program and therefore the efficiency of any breeding procedures. The success is usually measured by yield increase, commercial appeal and environmental adaptability of the developed germplasm.

The development of new soybean cultivars most often requires the development of hybrid crosses (some exceptions being initial development of mutants directly through the use of the mutating agent, certain materials introgressed by markers, or transformants made directly through transformation methods) and the selection of progeny. Hybrids can be achieved by manual manipulation of the sexual organs of the soybean or by the use of male sterility systems. Breeders often try to identify true hybrids by a readily identifiable trait or the visual differences between inbred and hybrid material. These heterozygous hybrids are then selected and repeatedly selfed and reselected to form new homozygous soybean lines.

Mass and recurrent selection can be used to improve populations. Several parents are intercrossed and plants are selected based on selected characteristics like superior yield or excellent progeny resistance. Outcrossing to a number of different parents creates fairly heterozygous breeding populations.

Pedigree breeding is commonly used with two parents that possess favorable, complementary traits. The parents are crossed to form a F1 hybrid. The progeny of the F1 hybrid is selected and the best individual F2s are selected; this selection process is repeated in the F3 and F4 generations. The inbreeding is carried forward and at approximately F5-F7 the best lines are selected and tested in the development stage for potential usefulness in a selected geographic area.

In backcross breeding a genetic allele or loci is often transferred into a desirable homozygous recurrent parent. The trait from the donor parent is tracked into the recurrent parent. The resultant plant is bred to be like the recurrent parent with the new desired allele or loci.

The single-seed descent method involves use of a segregating plant population for harvest of one seed per plant. Each seed sample is planted and the next generation is formed. When the F2 lines are advanced to approximately F6 or so, each plant will be derived from a different F2. The population will decline due to failure of some seeds, so not all F2 plants will be represented in the progeny.

New varieties must be tested thoroughly to compare their development with commercially available soybeans. This testing usually requires at least two years and up to six years of comparisons with other commercial soybeans. Varieties that lack the entire desirable package of traits can be used as parents in new populations for further selection or are simply discarded. The breeding and associated testing process is 8 to 12 years' of work prior to development of a new variety. Thousands of varietal lines are produced but only a few lines are selected in each step of the process. Thus the breeding system is like a funnel with numerous lines and selections in the first few years and fewer and fewer lines in the middle years until one line is selected for the final development testing.

The selected line or variety will be evaluated for its growth, development and yield. These traits of a soybean are a result of the variety's genetic potential interacting with its environment. All varieties have a maximum yield potential that is predetermined by its genetics. This hypothetical potential for yield is only obtained when the environmental conditions are near perfect. Since perfect growth conditions do not exist, field experimentation is necessary to provide the environmental influence and to measure its effect on the development and yield of the soybean. The breeder attempts to select for an elevated soybean yield potential under a number of different environmental conditions.

Selecting for good soybean yield potential in different environmental conditions is a process that requires planning based on the analysis of data in a number of seasons. Identification of the varieties carrying a superior combination of traits, which will give consistent yield potential, is a complex science. The desirable genotypic traits in the variety can often be masked by other plant traits, unusual weather patterns, diseases, and insect damage. One widely employed method of identifying a superior plant with such genotypic traits is to observe its performance relative to commercial and experimental plants in replicated studies. These types of studies give more certainty to the genetic potential and usefulness of the plant across a number of environments.

In summary, the goal of the soybean plant breeder is to produce new and unique soybeans and progeny of the soybeans for farmers' commercial crop production. To accomplish this, the plant breeder painstakingly crosses two or more varieties or germplasm. Then the results of this cross are repeatedly selfed or backcrossed to produce new genetic patterns. Newer avenues for producing new and unique genetic alleles in soybeans include introducing (or creating) mutations or transgenes into the genetic material of the soybean are now in practice in the breeding industry. These genetic alleles can alter pest resistance such as disease resistance, insect resistance, nematode resistance, herbicide resistance, or they can alter the plant's environmental tolerances, or its seeds fatty acid compositions, the amount of oil produced, and/or the amino acid/protein compositions of the soybean plant or its seed.

The traits a breeder selects for when developing new soybeans are driven by the ultimate goal of the end user of the product. Thus if the goal of the end user is to resist a certain plant disease so overall more yield is achieved, then the breeder drives the introduction of genetic alleles and their selection based on disease resistant levels shown by the plant. On the other hand, if the goal is to produce specific fatty acid composition, with for example a high level of oleic acid and/or a lower level of linolenic acid, then the breeder may drive the selection of genetic alleles/genes based on inclusion of mutations or transgenes that alter the levels of fatty acids in the seed. Reaching this goal may allow for the acceptance of some lesser yield potential or other less desirable agronomic trait.

The new genetic alleles being introduced into soybeans are widening the potential uses and markets for the various products and by-products of the oil from seed plants such as soybean. A major product extracted from soybeans is the oil in the seed. Soybean oil is employed in a number of retail products such as cooking oil, baked goods, margarines and the like. Another useful product is soybean meal, which is a component of many foods and animal feedstuffs.

This includes the introduction of at least one FRT site that may be used in the FLP/FRT system and/or a Lox site that may be used in the Cre/Lox system. For example, see Lyznik et al. (2003) Plant Cell Rep 21:925-932; and WO99/25821, which are hereby incorporated by reference. Other systems that may be used include the Gin recombinase of phage Mu (Maeser et al. (1991) Mol Gen Genet 230:170-176); the Pin recombinase of E. coli (Enomoto et al. (1983) J Bacteriol 156:663-668); and the R/RS system of the pSRI plasmid (Araki et al. (1992) J Mol Biol 182:191-203).

This invention embodies a method of introducing a desired trait into soybean variety derived from AR1319046 wherein the method comprises: (a) crossing a AR1319046 plant with a plant of another soybean variety that comprises a desired trait to produce new progeny plants, wherein the desired trait is selected from the group comprising male sterility, herbicide resistance, disease resistance, insect resistance, modified fatty acid metabolism, modified carbohydrate metabolism, and resistance to bacterial disease, fungal disease or viral disease; (b) selecting one or more new progeny plants that have the desired trait to produce selected progeny plants; (c) selfing selected progeny plants or crossing the selected progeny plants with the AR1319046 plants to produce late generation selected progeny plants; (d) crossing or further selecting for later generation selected progeny plants that have the desired trait and physiological and morphological characteristics of soybean variety AR1319046 to produce selected next later generation progeny plants; and optionally (e) repeating crossing or selection of later generation progeny plants to produce progeny plants that comprise the desired trait and all of the physiological and morphological characteristics of said desired trait and of soybean variety AR1319046 when grown in the same location and in the same environment.

The present invention further covers a method for producing a soybean seed with the steps of crossing at least two parent soybean plants and harvesting the hybrid soybean seed, wherein at least one parent soybean plant is the present invention. Another aspect of the invention covers the hybrid soybean seed and the progeny soybean plant and resultant seed, or parts thereof from the hybrid seed or plant or its progeny.

Yet another aspect of the invention covers a method for a breeding program using plant breeding techniques which employ the soybean plant AR1319046 as plant breeding material and performing breeding by selection techniques, backcrossing, pedigree breeding, marker enhanced selection, locus conversion, mutation and transformation. A single locus conversion of a site-specific recombination system allows for the integration of multiple desired traits at a known recombination site in the genome.

In an additional aspect, the invention covers a method for producing an inbred soybean plant derived from soybean variety AR1319046 by crossing soybean line AR1319046 with a second soybean plant to yield progeny soybean seed, and then growing a progeny plant and crossing said plant with itself or a second progeny plant to produce a progeny plant of a subsequent generation, and then repeating these steps for further subsequent generations to produce an inbred soybean plant derived from soybean variety AR1319046.

Trait Definitions

Hypocotyl Length (Hyp_R) A rating of a variety's hypocotyl extension after germination when planted at a 5″ depth in sand and maintained in a warm germination environment for 10 days.

Leaf Shape Calculated A calculated trait that divides length by width amongst 5 different leaf samples per replicate, measured in cm. 1=lanceolate; 2=oval; 3=ovate.

Seedling Establishment (EMRGR) A rating of uniform establishment and growth of seedlings. Rating is taken between the V1 and V3 growth stages and is a 1 to 9 rating with 1 being the best stand establishment.

Seed Coat Peroxidase (Perox)—seed protein peroxidase activity is a chemical taxonomic technique to separate cultivars based on the presence or absence of the peroxidase enzyme in the seed coat. Ratings are POS=positive for peroxidase enzyme or NEG=negative for peroxidase enzyme.

Chloride Sensitivity (CLS_T) An “Excluder” accumulates chloride and restricts the chloride in the roots. An “Includer” accumulates chloride throughout the plant. Based on molecular markers for analyzing chloride sensitivity, a chloride excluder carries a susceptible marker allele, and a chloride includer has a resistant allele.

Plant Height (PLHTN) The average measured plant height, in centimeters, of 5 uniform plants per plot, taken just prior to harvest.

Plant Branching (PLBRR) Rating of the number of branches and their relative importance to yield. This rating is taken at growth expressive locations. 1=no branching, 5=average and 9=profuse. Ratings taken just prior to harvest.

Green Lodging (GLDGR) Rating based on the average of plants leaning from vertical at the R5 to R6 growth stage. 1=all are erect, 5=average erectness. 9=all are flat. Rating of one is the best rating.

Harvest Lodging (HLDGR) Rating based on the average of plants leaning from vertical at harvest. Lodging score (1=completely upright, 5=45 degree angle from upright; 9=completely prostrate). Rating one is the best rating and ratings are taken just prior to harvest.

MON89788 The transgenic soybean event MON89788 carries a glyphosate tolerance transgene (U.S. Pat. No. 7,632,985 herein incorporated by reference). This transgene may be introgressed into a soybean variety, such that said variety now carries a glyphosate tolerance transgene.

MON87708 The transgenic soybean event MON87708 carries a transgene which expresses a dicamba mono-oxygenase, which confers tolerance to dicamba-based herbicides. This transgene may be introgressed into a soybean variety, such that said variety now carries a dicamba tolerance transgene.

Phytophthora Root Rot (PRR_R) means a Phytophthora Root Rot field tolerance rating. Rating is 1-9 with one being the best. The information can also include the listing of the actual resistance gene (RPS_T), for example, Rps gene 10.

Root Knot Nematode (RKN) Greenhouse screen—45 day screen of roots inoculated with eggs and juveniles. Rating Scale based upon female reproduction index on a susceptible check set determined by number of galls present on the root mass. Rating scale is 1-9 with 1 being best. Species specific ratings: Arenaria (MA_R), Incognita (MI_R), Javanica (MJ_R).

Stem Canker (Southern) (DPM_R) Greenhouse screen to identify vertical (gene) type of resistance. One week old soybean seedlings are inoculated with the stem canker pathogen by opening up a small slit into the hypocotyl and depositing a small drop of the fungal suspension. The inoculated seedlings are then placed into a moisture chamber. When the seedlings of the known checks have collapsed, disease severity rating are given on a 1-9 score. One being the best.

Stem canker (Southern) tolerance (DPMTR) Field nursery. The objective of this test is to evaluate the Field Resistance/Tolerance of soybean lines under field conditions. This is necessary due to the fact that of the four known genes that convey vertical type of resistance to stem canker, one gene (Rdc4 from the variety Dowling), exhibits a 40-50% plant kill (false positive) when screened in the greenhouse using the hypocotyl inoculation technique. Lines that scored a rating of 4-9 in the greenhouse are planted in the field. They are sprayed at least 5 times during their first month of development with a spore suspension containing the stem canker fungus. With the inclusion of very susceptible stem canker checks, we are able to identify horizontal (field resistance/tolerance) resistance in certain lines. Quite often, lines scoring a 9 in the greenhouse, rate a score of 1 in the field due to either having the Rdc4 gene or having good field resistance/tolerance. Disease severity scores are once again given on a 1-9 scale when the plants have reached the R6 growth stage of plant development. One being the best.

Brown Stem Rot (BSR_R) This disease is caused by the fungus Phialophora gregata. The disease is a late-season, cool-temperature, soil borne fungus which in appropriate favorable weather can cause up to 30 percent yield losses in soybean fields. BSR_R is an opportunistic field rating. The scale is 1-9. One rating is best.

Sudden Death Syndrome (SDS_R) This disease is caused by slow-growing strains of Fursarium solani that produce bluish pigments in the central part of the culture when produced on a PDA culture. The disease appears mainly in the reproductive growth stages (R2-R6) of soybeans. Normal diagnostics are distinctive scattered, intervienal chlorotic spots on the leaves. Yield losses may be total or severe in infected fields. The Sudden Death Syndrome Rating is both a field nursery and an opportunistic field rating. It is based on leaf area affected as defined by the Southern Illinois University method of SDS scoring. The scale used for these tests is 1-9. A one rating is best.

Sclerotinia White Mold (SCL_R) This disease is caused by the fungal pathogen Sclerotinia sclerotium. The fungus can overwinter in the soil for many years as sclerotia and infect plants in prolonged periods of high humidity or rainfall. Yield losses may be total or severe in infected fields. Sclerotinia White Mold (SCL_R) rating is a field rating (1-9 scale) based on the percentage of wilting or dead plants in a plot. A one rating is the best.

Frog Eye Leaf Spot (FELSR) This is caused by the fungal pathogen Cercospora sojina. The fungus survives as mycelium in infected seeds and in infested debris. With adequate moisture new leaves become infected as they develop until all the leaves are infected. Yield losses may be up to 15% in severe infected fields. Frog Eye Leaf Spot (FELSR) rating is a field rating (1-9 scale) based on the percentage of leaf area affected. The scale is 1-9 where 1=no leaf symptoms and 9=severe leaf symptoms. One is the best rating. To test varieties for Frog Eye Leaf Spot a disease nursery is artificially inoculated with spores. The ratings are done when the plants have reached the R5-R6 growth stage. Visual calibration is done with leaf photos of different frogeye severity ratings as used by the University of Tennessee and Dr. Melvin Newman, State Plant Pathologist for TN.

Soybean Cyst Nematode (SCN) The Soybean Cyst Nematode Heterodera glycines, is a small plant-parasitic roundworm that attacks the roots of soybeans. Soybean Cyst Nematode Ratings are taken from a 30 day greenhouse screen using cyst infested soil. The rating scale is based upon female reproduction index (FI %) on a susceptible check set ((female reproduction on a specific line/female reproduction on Susceptible check)*100) where <10%=R (RESISTANT); >10%-<30%=MR (MODERATELY RESISTANT); >30%-<60%=MS (MODERATELY SUSPECTIBLE); >60%=S (SUSPECTIBLE). The screening races include: 1, 3, 5, 14. Individual ratings CN1_P, CN3_P, CN5_P, and CN14_P refer to the resistance to SCN races 1, 3, 5 and 14 FI % respectively.

Powdery Mildew The name given to a group of diseases caused by several closely related fungi. Their common symptom is a grayish-white, powdery mat visible on the surface of leaves, stems, and flower petals. There are many hosts; and although this disease is not considered fatal, plant damage can occur when the infestation is severe.

Soybean Rust (Rust) Previously known as Asian soybean rust. This disease is caused by the fungus Phakopsora pachyrhiz.

Maturity Days from Planting (MRTYN) Plants are considered mature when 95% of the pods have reached their mature color. MRTYN is the number of days calculated from planting date to 95% mature pod color.

Relative Maturity Group (RM) Industry Standard for varieties groups, based on day length or latitude. Long day length (northern areas in the Northern Hemisphere) are classified as (Groups 000,00,0). Mid day lengths variety groups lie in the middle group (Groups I-VI). Very short day lengths variety groups (southern areas in Northern Hemisphere) are classified as (Groups VII, VIII, IX).

Grain Yield at Standard Moisture (YGSMN) The actual grain yield at standard moisture (13%) reported in the unit's bushels/acre.

Shattering (STR_R) The rate of pod dehiscence prior to harvest. Pod dehiscence is the process of beans dropping out of the pods. Advanced varieties are planted in a replicated nursery south of their adapted zone to promote early senescence. Mature plots are allowed to stand in the field to endure heat/cool and especially wet/dry cycles. Rating is based on the differences between varieties of the amount of open pods and soybeans that have fallen on the ground. The rating scale is 1-9 with 1=no shattering and 9=severe shattering. One rating is best.

The plant development staging system employed in the testing of this invention divides stages as vegetative (V) and reproductive (R). This system accurately identifies the stages of any soybean plant. However, all plants in a given field will not be in the stage at the same time. Therefore, each specific V or R stage is defined as existing when 50% or more of the plants in the field are in or beyond that stage.

The first two stages of V are designated a VE (emergence) and VC (cotyledon stage). Subdivisions of the V stages are then designated numerically as V1, V2, V3 through V (n). The last V stage is designated as V (n), where (n) represents the number for the last node stage of the specific variety. The (n) will vary with variety and environment. The eight subdivisions of the reproductive stages (R) states are also designated numerically. R1=beginning bloom; R2=full bloom; R3=beginning pod; R4=full pod; R5=beginning seed; R6=full seed; R7=beginning maturity; R8=full maturity.

Soybean Cultivar AR1319046

The present invention comprises a soybean plant, plant part, and seed, characterized by molecular and physiological data obtained from the representative sample of said variety deposited with the American Type Culture Collection. Additionally, the present invention comprises a soybean plant comprising the homozygous alleles of the variety, formed by the combination of the disclosed soybean plant or plant cell with another soybean plant or cell.

This soybean variety in one embodiment carries one or more transgenes, for example, the glyphosate tolerance transgene, a dicamba mono-oxygenase gene, a desaturase gene or other transgenes. In another embodiment of the invention, the soybean does not carry any herbicide resistance traits. In yet another embodiment of the invention, the soybean does not carry any transgenes but may carry alleles for aphid resistance, cyst nematode resistance and/or brown stem rot or the like.

The present invention provides methods and composition relating to plants, seeds and derivatives of the soybean cultivar AR1319046. Soybean cultivar AR1319046 has superior characteristics. The AR1319046 line has been selfed sufficient number of generations to provide a stable and uniform plant variety.

Cultivar AR1319046 shows no variants other than expected due to environment or that normally would occur for almost any characteristic during the course of repeated sexual reproduction. Some of the criteria used to select in various generations include: seed yield, emergence, appearance, disease tolerance, maturity, plant height, and shattering data.

The inventor believes that AR1319046 is similar in relative maturity to the comparison varieties. However, as shown in the figures and table, AR1319046 differs from these cultivars.

Direct comparisons were made between AR1319046 and the listed commercial varieties. Traits measured may include yield, maturity, lodging, plant height, branching, field emergence, and shatter. The results of the comparison are presented in the table below. The number of tests in which the varieties were compared is shown with the environments, mean and standard deviation for some traits.

The present invention AR1319046 can carry genetic engineered recombinant genetic material to give improved traits or qualities to the soybean. For example, but not limited to, the present invention can carry the glyphosate resistance gene for herbicide resistance as taught in the Monsanto patents (WO92/00377, WO92/04449, U.S. Pat. No. 5,188,642 and U.S. Pat. No. 5,312,910), or a gene which confers tolerance to dicamba-based herbicides, or the STS mutation for herbicide resistance. Additional traits carried in transgenes or mutation can be transferred into the present invention. Some of these genes include genes that give disease resistance to sclerotinia such as the oxalate oxidase (Ox Ox) gene as taught in PCT/FR92/00195 Rhone Polunc and/or an oxalate decarboxylase gene for disease resistance or genes designed to alter the soybean oil within the seed such as desaturase, thioesterase genes (shown in EP0472722, U.S. Pat. No. 5,344,771) or genes designed to alter the soybean's amino acid characteristics. This line can be crossed with another soybean line which carries a gene that acts to provide herbicide resistance or alter the saturated and/or unsaturated fatty acid content of the oil within the seed, or the amino acid profile of the seed. Thus through transformation or backcrossing of the present invention with a transgenic line carrying the desired event, the present invention further comprise a new transgenic event that is heritable. Some of the available soybean transgenic events include 11-234-01p Dow Soybean 2, 4-D, Glyphosate and Glufosinate Tolerant/DAS-444Ø6-6; 11-202-01p Monsanto Soybean Increased Yield/MON 87712; 10-188-01p Monsanto Soybean Dicamba Tolerant/MON 87708; 09-015-01p BASF Soybean Imadazolinone Tolerant/BPS-CV127-9; 09-328-01p Bayer Soybean Glyphosate and Isoxaflutole Tolerant/FG72; 09-201-01p Monsanto Soybean Improved Fatty Acid Profile/MON 87705; 09-183-01p Monsanto Soybean Stearidonic Acid Produced/MON 87769; 09-082-01p Monsanto Soybean Insect Resistant/MON 87701; 06-354-01p Pioneer Soybean High Oleic Acid/Event 305423; 06-271-01p Pioneer Soybean Glyphosate & Acetolactate Synthase Tolerant/DP-356Ø43-5; 06-178-01p Monsanto Soybean Glyphosate Tolerant/MON 89788; 98-238-01p AgrEvo Soybean Phosphinothricin Tolerant/GU262; 97-008-01p Du Pont Soybean High Oleic Acid Oil/G94-1, G94-19, G-168; 96-068-01p AgrEvo Soybean Glufosinate Tolerant/W62, W98, A2704-12, A2704-21, A5547-35; 96-068-01p AgrEvo Soybean Glufosinate Tolerant/W62, W98, A2704-12, A2704-21, A5547-35; 93-258-01p Monsanto Soybean Glyphosate Tolerant/4-30-2.

The present invention can also carry herbicide tolerance where the tolerance is conferred to an herbicide selected from the group consisting of glyphosate, glufosinate, acetolactate synthase (ALS) inhibitors, hydroxyphenylpyruvate dioxygenase (HPPD) inhibitors, protoporphyrinogen oxidase (PPO) inhibitors, phytoene desaturase (PDS) inhibitors, photosystem II (PSII) inhibitors, dicamba and 2,4-D.

This invention also is directed to methods for producing a new soybean plant by crossing a first parent plant with a second parent plant wherein the first or second parent plant is the present invention. Additionally, the present invention may be used in the variety development process to derive progeny in a breeding population or crossing. Further, both first and second parent plants can be or be derived from the soybean line AR1319046. A variety of breeding methods can be selected depending on the mode of reproduction, the trait, the condition of the germplasm. Thus, any such methods using the AR1319046 are part of this invention: selfing, backcrosses, recurrent selection, mass selection and the like.

The scope of the present invention includes use of marker methods. In addition to phenotypic observations, the genotype of a plant can also be examined. There are many techniques or methods known which are available for the analysis, comparison and characterization of plant's genotype and for understanding the pedigree of the present invention and identifying plants that have the present invention as an ancestor; among these are Isozyme Electrophoresis, Restriction Fragment Length Polymorphisms (RFLPs), Randomly Amplified Polymorphic DNAs (RAPDs), Arbitrarily Primed Polymerase Chain Reaction (AP-PCR), DNA Amplification Fingerprinting (DAF), Sequence Characterized Amplified Regions (SCARs), Amplified Fragment Length Polymorphisms (AFLPs), and Simple Sequence Repeats (SSRs) which are also referred to as Microsatellites.

The present invention also includes methods of isolating nucleic acids from a plant, a plant part, or a seed of the soybean variety, analyzing said nucleic acids to produce data, and recording said data. In some embodiments, the data may be recorded on a computer readable medium. The data may comprise a nucleic acid sequence, a marker profile, a haplotype, or any combination thereof. In some embodiments, the data may be used for crossing, selection, or advancement decisions in a breeding program.

A backcross conversion, transgene, or genetic sterility factor, may be in an embodiment of the present invention. Markers can be useful in their development, such that the present invention comprising backcross conversion(s), transgene(s), or genetic sterility factor(s), and are identified by having a molecular marker profile with a high percent identity such as 95%, 96%, 97%, 98%, 99%, 99.5% or 99.9% identical to the present invention.

These embodiments may be detected using measurements by either percent identity or percent similarity to the deposited material. These markers may detect progeny plants identifiable by having a molecular marker profile of at least 25%, 30%, 35%, 40%, 45%, 50%, 55%, 60%, 65%, 70%, 75%, 76%, 77%, 78%, 79%, 80%, 81%, 82%, 83%, 84%, 85%, 86%, 87%, 88%, 89%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99% or 99.5% genetic contribution from an embodiment of the present soybean variety. Such progeny may be further characterized as being within a pedigree distance of 1, 2, 3, 4 or 5 or more cross-pollinations to a soybean plant other than the present invention or a plant that has the present invention as a progenitor. Molecular profiles may be identified with SNP, Single Nucleotide Polymorphism, or other tools also.

Traits are average values for all trial locations, across all years in which the data was taken. In addition to the visual traits that are taken, the genetic characteristic of the plant can also be characterised by its genetic marker profile. The profile can interpret or predict the pedigree of the line, the relation to another variety, determine the accuracy of a listed breeding strategy, or invalidate a suggested pedigree. Soybean linkage maps were known by 1999 as evidenced in Cregan et. al, “An Integrated Genetic Linkage Map of the Soybean Genome” Crop Science 39:1464 1490 (1999); and using markers to determine pedigree claims was discussed by Berry et al., in “Assessing Probability of Ancestry Using Simple Sequence Repeat Profiles: Applications to Maize Inbred Lines and Soybean Varieties” Genetics 165:331 342 (2003), each of which are incorporated by reference herein in their entirety. Markers include but are not limited to Restriction Fragment Length Polymorphisms (RFLPs), Randomly Amplified Polymorphic DNAs (RAPDs), Arbitrarily Primed Polymerase Chain Reaction (AP-PCR), DNA Amplification Fingerprinting (DAF), Sequence Characterized Amplified Regions (SCARs), Amplified Fragment Length Polymorphisms (AFLPs), Simple Sequence Repeats (SSRs) which are also referred to as Microsatellites, and Single Nucleotide Polymorphisms (SNPs). There are known sets of public markers that are being examined by ASTA and other industry groups for their applicability in standardizing determinations of what constitutes an essentially derived variety under the US Plant Variety Protection Act. However, these standard markers do not limit the type of marker and marker profile which can be employed in breeding or developing backcross conversions, or in distinguishing varieties or plant parts or plant cells, or verify a progeny pedigree. Primers and PCR protocols for assaying these and other markers are disclosed in the Soybase (sponsored by the USDA Agricultural Research Service and Iowa State University) located at the world wide web at 129.186.26.94/SSR.html.

Additionally, these markers such as SSRs, RFLP's, SNPs, Ests, AFLPs, gene primers, and the like can be developed and employed to identify genetic alleles which have an association with a desired trait. The allele can be used in a marker assisted breeding program to move traits (native, nonnative (from a different species), or transgenes) into the present invention. The value of markers includes allowing the introgression and/or locus conversion of the allele(s)/trait(s) into the desired germplasm with little to no superfluous germplasm being dragged from the allele/trait donor plant into the present invention. This results in formation of the present invention for example, cyst nematode resistance, brown stem rot resistance, aphid resistance, Phytophthora resistance, IDC resistance, BT genes, male sterility genes, glyphosate tolerance genes, Dicamba tolerance, HPPD tolerance, rust tolerance, Asian Rust tolerance, fungal tolerance, or drought tolerance genes. Additionally, the invention through transgenes, or if a native trait through markers or backcross breeding, can include a polynucleotide encoding phytase, FAD-2, FAD-3, galactinol synthase or a raffinose synthetic enzyme; or a polynucleotide conferring resistance to soybean cyst nematode, brown stem rot, phytophthora root rot, or sudden death syndrome or resistance, tolerance to FUNGAL DISEASES such as: Alternaria spp., Agrobacterium rhizogenes, Calonectria crotalariae, Cercospora kikuchii, Cercospora sojina, Choanephora infundibulifera, Colletotrichum spp., Corynespora cassiicola, Curtobacterium flaccumfaciens, Dactuliochaeta glycines, Diaporthe phaseolorum, Fusarium oxysporum, Macrophomina phaseolina, Microsphaera difusa, Peronospora manshurica, Phakopsora pachyrhizi, Phialophora gregata, Phomopsis phaseolorum, Phyllosticta sojicola, Phytophthora sojae, Pseudomonas syringae, Pythium spp., Rhizoctonia solana, Sclerotinia sclerotiorum, Sclerotium rolfsii, Septoria glycines, Sphaceloma glycines, Thielaviopsis basicota; or tolerance to BACTERIAL and VIRAL DISEASES such as: Xanthomonas campestres, Cowpea Chlorotic Mottle Virus (CCMV), Peanut Mottle Virus (PMV), Tobacco Streak Virus (TSV), Bean Yellow Mosaic Virus (BYMV), Black Gram Mottle Virus (BGMV), Cowpea Mild Mottle Virus (CMMV), Cowpea Severe Mosaic Virus (CSMV), Indonesian Soybean Dwarf Virus (ISDV), Mung Bean Yellow Mosaic Virus (MYMV), Peanut Stripe Virus (VPMM), Soybean Chlorotic Mottle Virus, Soybean Crinkle Leaf Virus, Soybean Yellow Vein Virus (SYVV), Tobacco Mosaic Virus (TMV); NEMATODES such as: Belonolaimus gracilis, Meloidogyne spp, Rotylenchulus reniformis, Pratylenchus spp., Hoplolaimus sulumbus, Heterodera schachtii.

Many traits have been identified that are not regularly selected for in the development of a new cultivar. Using materials and methods well known to those persons skilled in the art, traits that are capable of being transferred, to cultivar of the present invention include, but are not limited to, herbicide tolerance, resistance for bacterial, fungal, or viral disease, nematode resistance, insect resistance, enhanced nutritional quality, such as oil, starch and protein content or quality, improved performance in an industrial process, altered reproductive capability, such as male sterility or male/female fertility, yield stability and yield enhancement. Other traits include the production of commercially valuable enzymes or metabolites within the present invention.

A transgene typically comprises a nucleotide sequence whose expression is responsible or contributes to the trait, under the control of a promoter capable of directing the expression of the nucleotide sequence at the desired time in the desired tissue or part of the plant. Constitutive, tissue-specific or inducible promoters are well known in the art and have different purposes and each could be employed. The transgene(s) may also comprise other regulatory elements such as for example translation enhancers or termination signals. The transgene may be adapted to be transcribed and translated into a protein, or to encode RNA in a sense or antisense orientation such that it is not translated or only partially translated.

Transgenes may be directly introduced into the cultivar using genetic engineering, site specific insertion techniques, and transformation techniques well known in the art or introduced into the cultivar through a process which uses a donor parent which has the transgene(s) already introgressed. This process of introduction of a transgene(s) or native/non-native traits into the cultivar may use the donor parent in a marker assisted trait conversion process, where the trait may be moved for example by backcrossing using the markers for selection of subsequent generations.

The laboratory-based techniques described above, in particular RFLP and SSR, can be used in such backcrosses to identify the progenies having the highest degree of genetic identity with the recurrent parent. This permits one to accelerate the production of soybean cultivars having at least 90%, 95%, 99% genetic, or genetically identical to the recurrent parent, and further comprising the trait(s) introgressed from the donor parent. Such determination of genetic identity can be based on markers used in the laboratory-based techniques described above.

The last backcross generation is then selfed to give pure breeding progeny for the gene(s) being transferred. The resulting plants have essentially all of the morphological and physiological characteristics of cultivar of the present invention, in addition to the gene trait(s) transferred to the inbred. The exact backcrossing protocol will depend on the trait being altered to determine an appropriate testing protocol. Although backcrossing methods are simplified when the trait being transferred is a dominant allele, a recessive allele may also be transferred. In this instance it may be necessary to introduce a test of the progeny to determine if the desired trait has been successfully transferred.

In general, methods to transform, modify, edit or alter plant endogenous genomic DNA include altering the plant native DNA sequence or a pre-existing transgenic sequence including regulatory elements, coding and non-coding sequences. These methods can be used, for example, to target nucleic acids to pre-engineered target recognition sequences in the genome. Such pre-engineered target sequences may be introduced by genome editing or modification. As an example, a genetically modified plant variety is generated using “custom” or engineered endonucleases such as meganucleases produced to modify plant genomes (see e.g., WO 2009/114321; Gao et al. (2010) Plant Journal 1:176-187). Another site-directed engineering method is through the use of zinc finger domain recognition coupled with the restriction properties of restriction enzyme. See e.g., Umov, et al., (2010) Nat Rev Genet. 11(9):636-46; Shukla, et al., (2009) Nature 459 (7245):437-41. A transcription activator-like (TAL) effector-DNA modifying enzyme (TALE or TALEN) is also used to engineer changes in plant genome. See e.g., US20110145940, Cermak et al. (2011), Nucleic Acids Res. 39(12) and Boch et al., (2009), Science 326(5959): 1509-12. Site-specific modification of plant genomes can also be performed using the bacterial type II CRISPR (clustered regularly interspaced short palindromic repeats)/Cas (CRISPR-associated) system. See e.g., Belhaj et al., (2013), Plant Methods 9: 39; The Cas9/guide RNA-based system allows targeted cleavage of genomic DNA guided by a customizable small noncoding RNA in plants (see e.g., WO 2015026883A1, incorporated herein by reference).

The cultivar of the invention can also be used for transformation where exogenous genes are introduced and expressed by the cultivar of the invention. Genetic variants created either through traditional breeding methods using cultivar of the present invention or through transformation of such cultivar by any of a number of protocols known to those of skill in the art are intended to be within the scope of this invention (see e.g. Trick et al. (1997) Recent Advances in Soybean Transformation, Plant Tissue Culture and Biotechnology, 3:9-26).

Transformation methods are means for integrating new genetic coding sequences (transgenes) into the plant's genome by the incorporation of these sequences into a plant through man's assistance. Many dicots including soybeans can easily be transformed with Agrobacterium. Methods of introducing desired recombinant DNA molecule into plant tissue include the direct infection or co-cultivation of plant cells with Agrobacterium tumefaciens, Horsch et al., Science, 227:1229 (1985). Descriptions of Agrobacterium vector systems and methods are shown in Gruber, et al., “Vectors for Plant Transformation, in Methods in Plant Molecular Biology & Biotechnology” in Glich et al., (Eds. pp. 89-119, CRC Press, 1993). Transformed plants obtained via protoplast transformation are also intended to be within the scope of this invention. Other transformation methods such as whiskers, aerosol beam, etc. are well known in the art and are within the scope of this invention. The most common method of transformation after the use of agrobacterium is referred to as gunning or microprojectile bombardment. This process has small gold-coated particles coated with DNA (including the transgene) shot into the transformable material. Techniques for gunning DNA into cells, tissue, explants, meristems, callus, embryos, and the like are well known in the prior art.

The DNA used for transformation of these plants clearly may be circular, linear, and double or single stranded.

Some of the time the DNA is in the form of a plasmid. The plasmid may contain additional regulatory and/or targeting sequences which assist the expression or targeting of the gene in the plant. The methods of forming plasmids for transformation are known in the art. Plasmid components can include such items as: leader sequences, transit polypeptides, promoters, terminators, genes, introns, marker genes, etc. The structures of the gene orientations can be sense, antisense, partial antisense or partial sense: multiple gene copies can be used.

After the transformation of the plant material is complete, the next step is identifying the cells or material, which has been transformed. In some cases, a screenable marker is employed such as the beta-glucuronidase gene of the uidA locus of E. coli. Then, the transformed cells expressing the colored protein are selected for either regeneration or further use. In many cases, a selectable marker identifies the transformed material. The putatively transformed material is exposed to a toxic agent at varying concentrations. The cells not transformed with the selectable marker, which provides resistance to this toxic agent, die. Cells or tissues containing the resistant selectable marker generally proliferate. It has been noted that although selectable markers protect the cells from some of the toxic effects of the herbicide or antibiotic, the cells may still be slightly affected by the toxic agent by having slower growth rates. If the transformed materials are cell lines then these lines are used to regenerate plants. The cells' lines are treated to induce tissue differentiation. Methods of regeneration of plants are well known in the art. General methods of culturing plant tissues are provided for example by Maki et al. “Procedures for Introducing Foreign DNA into Plants” in Methods in Plant Molecular Biology & Biotechnology, Glich et al. (Eds. pp. 67-88 CRC Press, 1993); and by Phillips et al. “Cell-Tissue Culture and In-Vitro Manipulation” in Soybean & Soybean Improvement, 3rd Edition Sprague et al. (Eds. pp. 345-387) American Society of Agronomy Inc. et al. 1988.

The plants from the transformation process or the plants resulting from a cross using a transformed line or the progeny of such plants which carry the transgene are transgenic plants.

The genes responsible for a specific gene trait are generally inherited through the nucleus. Known exceptions are, e.g. the genes for male sterility, some of which are inherited cytoplasmically, but still act as single gene traits. Male sterile soybean germplasm for hybrid soybean production was taught in U.S. Pat. No. 4,648,204. In a preferred embodiment, a transgene to be introgressed into the cultivar AR1319046 is integrated into the nuclear genome of the donor, non-recurrent parent or the transgene is directly transformed into the nuclear genome of cultivar AR1319046. In another embodiment of the invention, a transgene to be introgressed into cultivar AR1319046 is integrated into the plastid genome of the donor, non-recurrent parent or the transgene is directly transformed into the plastid genome of cultivar AR1319046. In a further embodiment of the invention, a plastid transgene comprises a gene that has transcribed from a single promoter, or two or more genes transcribed from a single promoter.

In another embodiment of the invention, DNA sequences native to soybean as well as non-native DNA sequences can be transformed into the soybean cultivar of the invention and used to alter levels of native or non-native proteins. Various promoters, targeting sequences, enhancing sequences, and other DNA sequences can be inserted into the genome for the purpose of altering the expression of proteins. Reduction of the activity of specific genes (also known as gene silencing or gene suppression) is desirable for several aspects of genetic engineering in plants.

Many techniques for gene silencing are well known to one of skill in the art, including but not limited to, knock-outs (such as by insertion of a transposable element such as mu (Vicki Chandler, The Maize Handbook Ch. 118 (Springer-Verlag 1994)); antisense technology (see, e.g., Sheehy et al. (1988) PNAS USA 85:8805-8809; and U.S. Pat. Nos. 5,107,065; 5,453,566; and 5,759,829); co-suppression (e.g., Taylor (1997) Plant Cell 9:1245; Jorgensen (1990) Trends Biotech 8:340-344; Flavell (1994) PNAS USA 91:3490-3496; Finnegan et al. (1994) Bio/Technology 12:883-888; and Neuhuber et al. (1994) Mol Gen Genet 244:230-241); RNA interference (Napoli et al. (1990) Plant Cell 2:279-289; U.S. Pat. No. 5,034,323; Sharp (1999) Genes Dev 13:139-141; Zamore et al. (2000) Cell 101:25-33; and Montgomery et al. (1998) PNAS USA 95:15502-15507); virus-induced gene silencing (Burton et al. (2000) Plant Cell 12:691-705; Baulcombe (1999) Curr Op Plant Biol 2:109-113); target-RNAspecific ribozymes (Flaselolf et al. (1988) Nature 334: 585-591); hairpin structures (Smith et al. (2000) Nature 407:319-320; WO99/53050; WO98/53083); microRNA (Aukerman & Sakai (2003) Plant Cell 15:2730-2741); ribozymes (Steinecke et al. (1992) EMBO J 11:1525; Perriman et al. (1993) Antisense Res Dev 3:253); oligonucleotide mediated targeted modification (e.g, WO03/076574 and WO99/25853); Zn-finger targeted molecules (e.g, WO01/52620; WO03/048345; and WO00/42219); use of exogenously applied RNA (e.g, US20110296556); and other methods or combinations of the above methods known to those of skill in the art.

A non-exclusive list of traits or nucleotide sequences capable of being transferred into cultivar AR1319046, using material and methods well known to those persons skilled in the art are as follows: genetic factor(s) responsible for resistance to brown stem rot (U.S. Pat. No. 5,689,035) or resistance to cyst nematodes (U.S. Pat. No. 5,491,081); a transgene encoding an insecticidal protein, such as, for example, a crystal protein of Bacillus thuringiensis or a vegetative insecticidal protein from Bacillus cereus, such as VIP3 (see, for example, Estruch et al. Nat Biotechnol [1997] 15:137-41); a herbicide tolerance transgene whose expression renders plants tolerant to the herbicide, for example, expression of an altered acetohydroxyacid synthase (AHAS) enzyme confers upon plants tolerance to various imidazolinone or sulfonamide herbicides (U.S. Pat. No. 4,761,373.) Other traits capable of being transformed into cultivar AR1319046 include, for example, a non-transgenic trait conferring to cultivar AR1319046 tolerance to imidazolinones or sulfonylurea herbicides; a transgene encoding a mutant acetolactate synthase (ALS) that renders plants resistant to inhibition by sulfonylurea herbicides (U.S. Pat. No. 5,013,659); a gene encoding a mutant glutamine synthetase (GS) resistant to inhibition by herbicides that are known to inhibit GS, e.g. phosphinothricin and methionine sulfoximine (U.S. Pat. No. 4,975,374); and a Streptomyces bar gene encoding a phosphinothricin acetyl transferase resulting in tolerance to the herbicide phosphinothricin or glufosinate (U.S. Pat. No. 5,489,520.)

Other genes capable of being transferred into the cultivar AR1319046 of the invention include tolerance to inhibition by cyclohexanedione and aryloxyphenoxypropanoic acid herbicides (U.S. Pat. No. 5,162,602), which is conferred by an altered acetyl coenzyme A carboxylase (ACCase); transgenic glyphosate tolerant plants, which tolerance is conferred by an altered 5-enolpyruvyl-3-phosphoshikimate (EPSP) synthase gene; tolerance to a protoporphyrinogen oxidase inhibitor, which is achieved by expression of a tolerant protoporphyrinogen oxidase enzyme in plants (U.S. Pat. No. 5,767,373.) Genes encoding altered protox resistant to a protox inhibitor can also be used in plant cell transformation methods. For example, plants, plant tissue or plant cells transformed with a transgene can also be transformed with a gene encoding an altered protox (See U.S. Pat. No. 6,808,904 incorporated by reference) capable of being expressed by the plant. The thus-transformed cells are transferred to medium containing the protox inhibitor wherein only the transformed cells will survive. Protox inhibitors contemplated to be particularly useful as selective agents are the diphenylethers (e.g. acifluorfen, 5-[2-chloro-4-(trifluoromethyl)phenoxy]-2-nitrobezoic acid; its methyl ester, or oxyfluorfen, 2-chloro-1-(3-ethoxy-4-nitrophenoxy)-4-(trifluorobenzene)), oxidiazoles, (e.g. oxidiazon, 3-[2,4-dichloro-5-(1-methylethoxy)phenyl]-5-(1,1-dimethylethyl)-1,3,4-oxadiazol-2-(3H)-one), cyclic imides (e.g. S-23142, N-(4-chloro-2-fluoro-5-propargyloxyphenyl)-3,4,5,6-tetrahydrophthalimide; chlorophthalim, N-(4-chlorophenyl)-3,4,5,6-tetrahydrophthalimide), phenyl pyrazoles (e.g. TNPP-ethyl, ethyl 2-[1-(2,3,4-trichlorophenyl)-4-nitropyrazolyl-5-oxy]propionate; M&B 39279), pyridine derivatives (e.g. LS 82-556), and phenopylate and its O-phenylpyrrolidino- and piperidinocarbamate analogs and bicyclic triazolones as disclosed in the International patent application WO 92/04827; EP 532146).

The method is applicable to any plant cell capable of being transformed with an altered protox-encoding gene, and can be used with any transgene of interest. Expression of the transgene and the protox gene can be driven by the same promoter functional on plant cells, or by separate promoters.

Modified inhibitor-resistant protox enzymes of the present invention are resistant to herbicides that inhibit the naturally occurring protox activity. The herbicides that inhibit protox include many different structural classes of molecules (Duke et al., Weed Sci. 39: 465 (1991); Nandihalli et al., Pesticide Biochem. Physiol. 43: 193 (1992); Matringe et al., FEBS Lett. 245: 35 (1989); Yanase and Andoh, Pesticide Biochem. Physiol. 35: (1989)), including the diphenylethers {e.g. acifluorifen, 5-[2-chloro-4-(trifluoromethyl)phenoxy]-2-nitrobezoic acid; its methyl ester; or oxyfluorfen, 2-chloro-1-(3-ethoxy-4-nitrophenoxy)-4-(trifluorobenzene)}, oxidiazoles (e.g. oxidiazon, 3-[2,4-dichloro-5-(1-methylethoxy)phenyl]-5-(1,1-dimethylethyl)-1,3,4-oxadiazol-2-(3H)-one), cyclic imides (e.g. S-23142, N-(4-chloro-2-fluoro-5-propargyloxyphenyl)-3,4,5,6-tetrahydrophthalimide; chlorophthalim, N-(4-chlorophenyl)-3,4,5,6-tetrahydrophthalimide), phenyl pyrazoles (e.g. TNPP-ethyl, ethyl 2-[1-(2,3,4-trichlorophenyl)-4-nitropyrazolyl-5-oxy]propionate; M&B 39279), pyridine derivatives (e.g. LS 82-556), and phenopylate and its O-phenylpyrrolidino- and piperidinocarbamate analogs.

Direct selection may be applied where the trait acts as a dominant trait. An example of a dominant trait is herbicide tolerance. For this selection process, the progeny of the initial cross are sprayed with the herbicide prior to the backcrossing. The spraying eliminates any plant that does not have the desired herbicide tolerance characteristic, and only those plants that have the herbicide tolerance gene are used in the subsequent backcross. This process is then repeated for the additional backcross generations.

In yet another embodiment of the present invention, a transgene transformed or introgressed into cultivar AR1319046 comprises a gene conferring tolerance to a herbicide and at least another nucleotide sequence for another trait, such as for example, insect resistance or tolerance to another herbicide. Another gene capable of being transferred into the cultivar AR1319046 of the invention expresses thioredoxin and thioredoxin reductase enzymes for modifying grain digestibility and nutrient availability (U.S. Pat. Appl. No. 20030145347.)

Further reproduction of the cultivar can occur by tissue culture and regeneration. Tissue culture of various tissues of soybeans and regeneration of plants therefrom is well known and widely published. For example, reference may be had to Komatsuda, T. et al., “Genotype X Sucrose Interactions for Somatic Embryogenesis in Soybean,” Crop Sci. 31:333-337 (1991); Stephens, P. A. et al., “Agronomic Evaluation of Tissue-Culture-Derived Soybean Plants,” Theor. Appl. Genet.

No. 5,024,944, issued Jun. 18, 1991 to Collins et al. and U.S. Pat. No. 5,008,200, issued Apr. 16, 1991 to Ranch et al. Thus, another aspect of this invention is to provide cells that upon growth and differentiation produce soybean plants having all or essentially all the physiological and morphological characteristics of cultivar AR1319046. The disclosures, publications, and patents that are disclosed herein are all hereby incorporated herein in their entirety by reference.

Sublines of soybean cultivar AR1319046 may also be developed and are provided. Although soybean cultivar AR1319046 contains substantially fixed genetics and is phenotypically uniform with no off types expected, there still remains a small proportion of segregating loci either within individuals or within the population as a whole. Sublining provides the ability to select for these loci, which have no apparent morphological or phenotypic effect on the plant characteristics, but may have an effect on overall yield. For example, the methods described in U.S. Pat. Nos. 5,437,697, 7,973,212, and US2011/0258733, and US2011/0283425 (each of which is herein incorporated by reference) may be utilized by a breeder of ordinary skill in the art to identify genetic loci that are associated with yield potential to further purify the variety in order to increase its yield. A breeder of ordinary skill in the art may fix agronomically relevant loci by making them homozygous in order to optimize the performance of the variety. The development of soybean sublines and the use of accelerated yield technology is a plant breeding technique.

The seed of soybean cultivar AR1319046 further comprising one or more specific, single gene traits, the plant produced from the seed, the hybrid soybean plant produced from the crossing of the cultivar with any other soybean plant, hybrid seed, and various parts of the hybrid soybean plant can be utilized for human food, livestock feed, and as a raw material in industry.

Soybean is the world's leading source of vegetable oil and protein meal. The oil extracted from soybeans is used for cooking oil, margarine, and salad dressings. Soybean oil is composed of saturated, monounsaturated and polyunsaturated fatty acids. It has a typical composition of 11% palmitic, 4% stearic, 25% oleic, 50% linoleic and 9% linolenic fatty acid content (“Economic Implications of Modified Soybean Traits Summary Report”, Iowa Soybean Promotion Board & American Soybean Association Special Report 92S, May 1990.) Changes in fatty acid composition for improved oxidative stability and nutrition are constantly sought after. (U.S. Pat.

Industrial uses of soybean oil that is subjected to further processing include ingredients for paints, plastics, fibers, detergents, cosmetics, and lubricants. Soybean oil may be split, inter-esterified, sulfurized, epoxidized, polymerized, ethoxylated, or cleaved. Designing and producing soybean oil derivatives with improved functionality, oliochemistry is a rapidly growing field. The typical mixture of triglycerides is usually split and separated into pure fatty acids, which are then combined with petroleum-derived alcohols or acids, nitrogen, sulfonates, chlorine, or with fatty alcohols derived from fats and oils.

The techniques of seed treatment application are well known to those skilled in the art, and they may be used readily in the context of the present invention. The seed treating compositions can be applied to the seed as slurry, mist or a soak or other means know to those skilled in the art of seed treatment. Seed treatments may also be applied by other methods, e.g., film coating or encapsulation. The coating processes are well known in the art, and employ, for seeds, the techniques of film coating or encapsulation, or for the other multiplication products, the techniques of immersion. Needless to say, the method of application of the compositions to the seed may be varied and is intended to include any technique that is to be used.

Soybean seeds, plants, and plant parts may be used or processed for food, animal feed, or a raw material(s) for industry. Soybean is not just a seed it is also used as a grain. Soybean is widely used as a source of protein for animal feeds for poultry, swine and cattle. The soybean grain is a commodity. The soybean commodity plant products include but are not limited to protein concentrate, protein isolate, soybean hulls, meal, flower, oil and the whole soybean itself. Soybean seeds can be crushed, or a component of the seeds can be extracted in order to make a plant product, such as protein concentrate, protein isolate, soybean hulls, meal, flour, or oil for a food or feed product. Methods of producing a plant product, such as protein concentrate, protein isolate, soybean hulls, meal, flour, or oil for a food or feed product are provided. Also provided are the protein concentrate, protein isolate, soybean hulls, meal, flour, or oil produced by the methods.

Oil extracted from soybeans is used for cooking oil, margarine, and salad dressings. Soybean oil has a typical composition of 11% palmitic, 4% stearic, 25% oleic, 50% linoleic, and 9% linolenic fatty acid content. Industrial uses of soybean oil, which is typically subjected to further processing, include ingredients for paints, plastics, fibers, detergents, cosmetics, lubricants, and biodiesel fuel. Soybean oil may be split, inter-esterified, sulfurized, epoxidized, polymerized, ethoxylated, or cleaved. To produce oil, the harvested soybeans are cracked, adjusted for moisture content, rolled into flakes, and then the oil is solvent-extracted. The oil extract is refined, optionally blended and/or hydrogenated. Some soybean varieties have modified fatty acid profiles and can be used to produce soybean oil with a modified fatty acid composition. Oil with 3% or less linolenic acid is classified as low linolenic oil, oil with less than 1% linolenic acid is classified as ultra low linolenic oil. Oil with 70% or higher of oleic acid is classified as high oleic oil.

Soybeans are also used as a food source for both animals and humans. Soybeans are widely used as a source of protein for animal feed. The fibrous hull is removed from whole soybean and the oil is extracted. The remaining meal is a combination of carbohydrates and approximately 50% protein. This remaining meal is heat treated under well-established conditions and ground in a hammer mill. Soybean is a predominant source for livestock feed components. In addition to soybean meal, soybean can be used to produce soy flour. Soy flour refers to defatted soybeans where special care was taken during desolventizing to minimize protein denaturation and to retain a high nitrogen solubility index (NSI) in making the flour. Soy flour is the typical starting material for production of soy concentrate and soy protein isolate. Defatted soy flour is obtained from solvent extracted flakes, and contains less than 1% oil. Full-fat soy flour is made from whole beans and contains about 18% to 20% oil. Low-fat soy flour is made by adding back some oil to defatted soy flour. The lipid content varies, but is usually between 4.5-9%. High-fat soy flour can also be produced by adding soybean oil to defatted flour at the level of 15%. Lecithinated soy flour is made by adding soybean lecithin to defatted, low-fat or high-fat soy flours to increase dispersibility and impart emulsifying properties.

For human consumption, soybean can be used to produce edible ingredients which serve as an alternative source of dietary protein. Common examples include milk, cheese, and meat substitutes. Additionally, soybean can be used to produce various types of fillers for meat and poultry products. Vitamins and/or minerals may be added to make soy products nutritionally more equivalent to animal protein sources as the protein quality is already roughly equivalent.
